Amalgamation of Races

A/N:

I welcome everyone, whether returning readers or new readers to the rewrite of Overpowered "Human".

I have made some serious changes to what I originally wrote, so I will recommend that you read those changes.

To everyone reading this, READ THIS FIRST CHAPTER. This one chapter makes one of the biggest changes to the overall story, so everyone should read it.

However, if you're a returning reader and feel as though it's rather redundant to read the Kimestsu no Yaiba Ark again, then I will give you the privilege of skipping over chapters 2-19 (which are the training and info dumps) and getting directly into the action provided in this Ark. If you are among the people who don't want to read it at all, then I ask you to wait patiently until chapter 50 comes into existence, then you can skip directly to the next Ark.

After saying that, please enjoy!

In a grand pitch-black space, if that is what it is to be called, we see a grey speck. This grey speck is a soul, neither pure nor evil, a complete balance between the two. If we were to look at this soul's thoughts, we would find a calm and collected thought process.

(Soul's POV)

'Huh, so I died. Not exactly how I wanted to go out in life, but I mean, what am I supposed to do when a plane comes flying through my bedroom window just to kill me.' I thought to myself. 'Damn you truck who drank red bull.'

Sighing to myself, I look around the black expanse to find, you guessed it, absolutely nothing. Being bored and wanting to do something with the seemingly endless amount of time that I've been given, I start to spin myself around.

Finding that I couldn't get dizzy, I steadily increased my speed until I was travelling at Mach 2.

As I continuing to spin, I thought to myself, 'I wonder how long I'll be staying in this purgatory for until I get reincarnated. I expected instantaneous reincarnation since I don't believe that any sort of God or astral being would want to talk with me, but I guess I'm stuck for now.'

'Actually, the more I think on it, I might stay in this purgatory for four thousand four hundred and forty-four days since my lucky number and soul number was four. My life pretty much revolved around that number, including my League of Legends main.'

Thinking about my last statement, I could only let out a short curse and think, 'Dang, I never managed to reach diamond before I died, Rip.'

Thinking how much nicer this experience would be if I could listen to music, I "close" my eyes and wait for the time to pass.

(Narration POV)

The soul of course continues to think about multiple things and with its eyes "closed", it didn't notice another soul starting to form in this grand pitch-black space. This soul, when compared to our MC, is pure white in color.

As more and more time passes, the white soul continues to grow larger until it is about 4x larger than the grey soul.

"Greeting's child." The white soul bellows out.

The grey soul, at hearing a voice other than the one in its head, immediately "opens" its eyes and stops spinning. Staring at the large soul in front of it, the grey soul doesn't say anything and waits for the white soul to continue.

Instead of continuing, the white soul starts to condense in on itself until it takes the form of a human being, astonishing the grey soul. The human has taken on the form of a well-built male with a neatly trimmed face and eyes as blue as the sky. The human then stares at the grey soul for a while before finally saying something.

"I'm rather surprised that anyone is in this purgatory. Normally people go through their own reincarnation chain that their world makes, but your soul has broken out of that cycle and is now travelling the multiverse reincarnation chain. How interesting."

The human then starts to fly around the soul, as if inspecting everything about it, before nodding his head in satisfaction.

"You'll do nicely." The human states. "I want to spice things up in the multiverse, and you are the ticket to do that as you can travel this multidimensional chain."

The grey soul stares at the human, again waiting for him to continue.

"I will give you one supreme wish that you can do anything with. You can of course determine your appearance and the time period you will appear in whatever world the wheel chooses." The human says while smirking.

"So, I can do anything with that wish?" The soul speaks for the very first time.

The human in return nods his head.

"Then, I wish that when I enter one of the multiverse worlds, I will receive wishes for every intelligent race and I can transform into each of those races."

The human then stares at me while nodding his head. "That's a pretty good wish and it will certainly make things interesting. Alright, I'll allow it, but the one setback is that you must have knowledge of the power of those races. This will both prevent you from spending a million years in a void to make your wishes and it will prevent the possibilities of a parasitic race from evolving. Also, you will be limited to a maximum of three races, if you know more, you get to choose which ones to wish for."

"That's fair." The grey soul says in return.

"Alright, with your wish out of the way, you can now form your appearance."

The human then claps his hands, and a screen appears in front of the soul. The soul looks at the screen with interest before figuring out that it could choose options by thinking about it with its mind.

The soul, after deliberating for an hour on its appearance choices chooses to be a male with the name of Shiro and have pure black hair, perfect blue eyes, pale skin that will easily burn in the sun, a partial androgyne face that is completely symmetrical, a compressed muscle build, and a height of 6' 1".

"Rather interesting options for how you want to look, but I won't judge." The human says while shrugging. "Anyway, with those two things out of the way, we shall now spin the wheel."

The human then chuckles before having a giant wheel appear next to him.

"Spin baby, spin!"

The wheel then starts spinning at an unimaginable speed to the point where it no longer looks like it's spinning. After a while though, the wheel starts to blur and then slows down at a considerable pace. Hearing the click of the flapper start happening less and less, the wheel finally comes to a stop. Slowly, the red tile unveils itself and shows the world.

"Seems like you managed to get the world of Demon Slayer: Kimetsu no Yaiba, a rather good starting place for you if I do say so myself."

The human then turns towards me. "Now, determine the location and age you want to appear in this world."

Deliberating for a time, the soul decides. "I want to be five years old with my birth year being the same as Tanjiro. For my location, I want to be put near the retired water Hashira other known as Sakonji Urokodaki."

"Alright." The human agrees.

"Now, before you leave, I will give you both improved comprehension and mastery because I'd rather you not spend most of your life on training rather than actually doing something. Also, you will receive a message in front of you whenever you finish the important mission of that world, and this message will both allow you to travel to your next world along with any companions you wish to bring along. When you travel to another world, you will once again determine your age and location. However, do know that your chosen age will also affect that of you companions."

"Now, after a certain number of worlds completed has been reached, you will be given the option of going to a safe world. However, if the world you spin in meant to be a single person world, then your companions will be safely teleported to the safe world and have a message left for them on what's going on."

The human then puts his hands together to form a triangle and a blinding ball of white forms in the triangle-shaped hole.

"Please do spice things up won't you."

"Lastly, the world you're going to has slightly changed, so if something doesn't make sense then it's most likely because I've changed that function, especially the age of some very important people. Goodbye."

The white light then travels towards the grey soul and starts to dematerialize it.

Before the soul is completely gone, the soul yells out, "Thank you!"

The human smiles brightly before lowering his arms and turning back into his white soul form. Opening a rift in front of itself, the white soul floats through and disappears.
